Avenue to create a 2-lane divided road on a temporary basis to address traffic calming, safety, and vehicle noise issues along the corridor. The City has also timed the traffic signal at Vineyard Avenue and Ruby I-Iill Boulevard to limit the amount of traffic that can enter the City from the east during the morning peak hour. The 1996 General Plan Roadway Network traffic model included the wider roadway features mentioned previously, and the intersection lane geometry shown in Figure 111-7. The model did assume continued metering of inbound traffic in the morning from the east. With this lane geometry, the model forecasts LOS C conditions at the intersection of Bemal Avenue at Vineyard Avenue during the morning peak hour and LOS D conditions in the evening. Like many of the other wide roadway segments in the City, this section was designed when a four-lane Vineyard Avenue segment would have extended all the way to Ruby Hill, with much more intensive development planned. The roadway is presently sufficiently wide for a divided four-lane road until the approach to Montevino Drive. The median has generally not been installed. The right-of-way narrows at Montevino Drive, and from there to Clara Lane, it is a high-capacity tow-lane road (with protect left-mm lane) pursuant to the Vineyard Avenue Corridor Specific Plan. Any widening of this section would be constrained. Funding for any revisions would be from City resources as there is no direct development which would contribute to any changes here. To analyze the pros and cons of the providing a 4-lane section along this portion of Vineyard Avenue from a traffic perspective, the traffic forecasting model was used to study roadway users during the morning and evening peak hour to assess: · Who would use the 4-lane roadway (local or cut-through)? · Where were Pleasanton drivers coming from or going to as they used the road? · What was the purpose of the trip (work, school, shop, recreation, etc.)? · What impact did the additional lanes have on driving times and driving distances for local drivers? · How did the 4-lane roadway affect traffic volumes at 135 City intersections? · How did the 4-lane roadway affect cut-through traffic in Pleasanton? The following is a summary of the traffic forecast model outputs. Morning Peak Hour 4-lane Vineyard Avenue Users The following map shows that about 1,000 Pleasanton drivers would use the 4-lane section of Vineyard Avenue if it were striped as shown in the 1996 General Plan Roadway Network. About 30 cut-through vehicles would use the roadway during the morning peak hour. This cut- through volume is restricted by the traffic signal at Ruby Hill Boulevard. The roadway acts as the sole link between Ruby Hill and the Vineyard Corridor Specific Plan Area and the rest of the SR 05:027 Page 50
